Patent JP-H10335581-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: OKUDAIRA TOMOHITO
IPC: H01L21/822
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain a good stable capacitor by providing a high-dielectric const. dielectric or ferroelectric at the interface between a capacitor upper electrode and capacitor upper layer insulation film. SOLUTION: A protective layer 8e is formed so that its thickness = (total thickness of part of a capacitor upper layer insulation film 9, framed oxide film 8d and capacitor lower layer insulation film 6)/etching selectivity. This prevents unwanted overetching in a contact hole 10 forming step on the capacitor. The thickness of BST having a lower etching rate than that of the silicon oxide film is controlled to form the protective film 8e on a cell plate electrode 8c and opening of the contact hole 10 on the capacitor and peripheral circuit at approximately the same time. This minimizes the damage to the cell plate electrode 8c due to a plasma for forming the contact hole 10 and prevents the loss of a barrier metal on the electrode 8c.

Title: Manufacture of epitaxial wafer and device for manufacturing semiconductor to be used for the same
Inventor: OTA YUTAKA
IPC: B08B3/08
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a pit accompanied with cleaning, by preventing metallic gains from being directly adhered to a silicon epitaxial layer. SOLUTION: An epitaxial wafer EPW obtained in a step S2 is carried from a reaction chamber in a step S3, and O3 water cleaning or SC1 cleaning is immediately operated in a step S4 so that a chemical silicon oxide film C can be formed on the surface of a silicon epitaxial layer E. Afterwards, even when the adhesion of metallic grains M is generated while prescribed measurement or inspection is operated in steps S5 and S6, oxidation/reduction reaction between a silicon epitaxial layer E and the metallic grains M can be suppressed by the chemical silicon oxide film C, and hard adhesion can be prevented. Thus, even when SC1+SC2 cleaning 13 operated in a step S7, any pit cannot be generated in the silicon epitaxial layer E.

IPC: F27B5/06
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To reduce heat dissipation to the outside of a furnace by improvement in heat insulation ability and to improve heat efficiency by constituting a furnace body wall of a double structure consisting of an inner shell and an outer shell, making a space between the inner shell and the outer shell into a closed decompression chamber and forming a radiation reflecting film on the opposing faces of the inner shell and the outer shell. SOLUTION: Preferably radiation reflecting layers use, for example, mirror plates layers, flame sprayed layers, foils, etc. and the outside of an inner shell is composed of a high-temperature heat-resistant material (e.g. stainless steel, foil, thin film, thin plate, etc. of titanium, etc.). The pressure of a closed decompression chamber is, for example, about 0.1 Torr. The closed decompression chamber communicates with a furnace in a vacuum furnace such as a vacuum smelting furnace. A furnace body 1 of a heating furnace for purifying silicon comprises an inner shell 2 and an outer shell 3 and a space between them is made into a closed decompression chamber under 0.1 Torr at a normal temperature.  An outer face radiation reflecting layer 5 of the inner shell 2 and an inner face radiation reflecting layer 6 of the outer shell 3 are coated with thin plates of stainless steel to reflect radiation. An atmosphere 7 in the furnace can communicate with the closed decompression chamber 4.

Title: Manufacture of metallic mold
Inventor: TAMURA KUNINORI
IPC: B22C7/02
Filed: 1988-06-08
Abstract: PURPOSE:To simply manufacture a pattern for manufacturing metallic mold having high accuracy by laminating and sticking plate-like bodies having the same outer shape based on outer shape. CONSTITUTION:Plural plate-like bodies 1a, 1b, 1c made of foaming styrene and having the same outer shape are cut with line 2 corresponding to outline of cross section of the metallic mold and divided into the cross section corresponding parts 3, outer waste parts 4 and holes as cast waste parts 4a. The plate like bodies 1a, 1b, 1c, which the above parts are not yet separated, are laminated under neatly fitting the outer shape while positioning the corner part 1d by using a positioning means. At the time of laminating the plate-like bodies 1a, 1b, 1c as such a way, the cross section corresponding parts 3 in the adjoining plate like bodies between the plate-like bodies 1a and 1b, and 1b and 1c, are stuck. In this way, the laminated plate-like bodies are stuck under positioning the cross section corresponding parts 3. Then, as the outer waste parts 4 and the holes as cast waste parts 4a do not apply the adhesive, separation of them after laminating can be executed. Therefore, by separating the outer waste parts 4 and the holes as cast waste parts 4a, the pattern 6 having the same shape as the metallic mold can be formed.

IPC: B29C49/64
Filed: 1988-06-08
Abstract: PURPOSE:To almost prevent the generation of heat shrinkage even when high temp. filling is performed by applying blow molding to a parison, which is formed from amorphous polyethylene terephthalate by injection molding, in a heated mold and quenching the molded body while holding the same to a pressurized state. CONSTITUTION:An amorphous polyethylene terephthalate resin is used to be molded into a parison having an arbitrary shape by injection molding and the molded parison is preheated before cooled perfectly and subjected to stretching blow molding to form, for example, a bottle-shape container. At this time, the surface temp. of a mold is set to 140 deg.C or higher and the polyethylene terephthalate constituting the container is set to crystallinity of 40% or more. Thereafter, the surface temp. of the mold is allowed to fall to 100 deg.C or lower while blow pressure is kept. Next, the blow pressure is released and the mold is opened to take out the bottle-shape container.

Title: Information reading device
Inventor: KATOU YOSHITSUGU
IPC: G06K7/10
Filed: 1977-11-24
Abstract: PURPOSE: To simplify the circuit constitution by providing a single-turn deflecting coil to the pickup tube which reads out the tag card and then varying the scanning direction to secure the readable state of the tag card through the rotary adjustment of the deflecting angle for the deflecting coil.  
     CONSTITUTION: Single-turn deflecting coil 1, using two units of the deflecting coil featuring the same impendance, is used. With supply of the saw-tooth waveform voltage to input terminal 2 of the constant current driving circuit, the current flowing to coil 1 is fed back to differential amplifier 4 by the function resistance 3, and accordingly the current of the saw-tooth waveform proportional to the input voltage flows to coil 1. In such way, the current flowing to coil 1 is changed to the saw-tooth waveform, so the polarity switching becomes easy when the deflecting angle is changed to an optional angle. And no transient is caused through switching.
